To provide a vehicular lighting tool capable of forming a predetermined light distribution pattern wide in the horizontal direction without increasing the number of light sources.SOLUTION: A vehicular lighting tool 10C to form the predetermined light distribution pattern including a plurality of light source images includes a plurality of light sources LS1-LS4, a plurality of projection lenses OP1-OP4 corresponding to the plurality of light sources LS1-LS4, and a magnification changing lens 14. A control system 20 includes a control part 21. To the control part 21, a lighting control circuit 22, an imaging device 23, a road surface status detection part 24, a weather detection part 25, a vehicle speed sensor 26, etc. are connected. The lighting control circuit 22 performs individual lighting-on/off (including dimming) control of a plurality of semiconductor light emitting elements (pixels) constituting the light sources LS1-LS4 in accordance with control from the control part 21.SELECTED DRAWING: Figure 27
【課題】光源の数を増やすことなく水平方向にワイドな所定配光パターンを形成することができる車両用灯具を提供する。【解決手段】複数の光源像を含む所定配光パターンを形成する車両用灯具10Cは、複数の光源LS1〜LS4と、複数の光源LS1〜LS4に対応する複数の投影レンズOP1〜OP4、倍率変更レンズ14とを備える。制御システム20は、制御部21を備える。制御部21には、点灯制御回路22、撮像装置23、路面状況検知部24、天候検知部25、車速センサ26等が接続されている。点灯制御回路22は、制御部21からの制御に従って光源LS1〜LS4を構成する複数の半導体発光素子(ピクセル)を個別に点消灯(減光を含む)制御する。【選択図】図27
